How Much Does a Solar Battery Cost? (2025–2026 Guide)
But one of the first questions homeowners ask is: how much does a solar battery actually cost in 2025, and what will change in 2026? The answer depends on the size, type,
A report from the National Renewable Energy Laboratory (NREL) estimates that a solar battery including installation can cost almost $19,000* to install, including the price of the battery itself and labor. Installation and permitting fees vary by location and installer, but the NREL estimates the battery itself typically costs $16,007.
If you're looking to buy battery storage for your solar panels, you can probably expect to pay between $7,000 and $18,000. Just know that the overall price range for a solar battery is even wider, with prices anywhere from a few hundred dollars to $30,000+, depending on what you buy, who you buy it from and how you plan to use it.
On EnergySage, Pytes USA Energy offers some of the most affordable batteries at about $651/kWh. You'll typically pay the most for Enphase batteries, which cost about $1,510/kWh. *The average price per kWh of the 10 most quoted batteries on EnergySage in the first half of 2025 (excluding Panasonic, which is closing its solar and storage business).
The downside is interest payments on the loan accrue over time to increase the overall cost of the system. For example, using the example from earlier, financing a 7.9 kW solar system and 12.5 kWh battery with a 20-year loan (with zero money down) would cost nearly $47,000 while paying cash would cost around $30,000.
